Celtics Jaylen Brown wrote and produced a song to help himself focusing before the games

Celtics forward Jaylen Brown wrote and produced a hip hop song, called Building Blocks, to help himself focusing before the games. The song, which lasts three minutes and thirty-one seconds, contains motivational lyrics that helped Brown when he needed to defend against a superstar like Lebron James. Here's an extract from the lyrics, as reported by SportTechie:

"Game day and it’s time to focus in. … Is you ready, I can feel you breathing heavy, keep it steady. I just gotta pretend that I got it all together when I don’t. Probably wanna throw up but I won’t … just breathe."
